Edgar Frank "Ted" Codd (19 August 1923 – 18 April 2003) was a British computer scientist who, while working for IBM, invented the relational model for database management, the theoretical basis for relational databases and relational database management systems.
He was the co-founder of Oracle Corporation and the producer of Oracle's relational database management system. [1] From 1977 until 1992, Miner led product design and development for the Oracle relational database management system.

Oracle has its own spin where creating a user is synonymous with creating a schema. Thus a database administrator can create a user called PROJECT and then create a table PROJECT.TABLE. Users can exist without schema objects, but an object is always associated with an owner (though that owner may not have privileges to connect to the database).
Significant technologies incorporated into the applications include the Oracle database technologies, (engines for RDBMS, PL/SQL, Java, .NET, HTML and XML), the "technology stack" (Oracle Forms Server, Oracle Reports Server, Apache Web Server, Oracle Discoverer, Jinitiator and Sun's Java).
